T0 ALL WHOM I'I MAY CONCERN:

B'e it known that I, ISAAC Monnet', of Pittsburg, in the county of Allegheny, `and State of Pennsylvania, have invented certain newA and useful improvements in Brick Machines; and I do hereby declare that the following' is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part or" this specification, and to the letters of reference marked thereon, like lettersindicating like parts wherever they occur. To enable others skilled in the art to construct and use my invention, I will proceed to describe it. l

My invention consists in certain improvements upon the machine heretofore patented to me for making brick, and consists `in a novel arrangement of devices whereby the machine is made to operate with greater perfection.

Figure 1 is a sideview.

Figure 2, an endview,

Figure 3, a. view of the side opposite to the side represented by iig. 1V; and

Figure 4 is a. view of a portion detached.

The machine consists of a frame, A, upon which is mounted a pug 'mill for grinding the clay, and which consists of the hopper B and the vertical shaft x, armed with the usual blades or arms r, for pulverizing the clay. Transversely of the hopper `B is arranged a screen, S, to prevent stones from passing below. Underneath the hopper B is a chamber, C, into whichthe clay passes from thc hopper B, it being pressed down by means of a screw diaphragm, W, attached to the lower end of shaft t, which latter shaft extends through the centre of shaft 5c, which is made tubular for that purpose. Motion is imparted to these shafts, :v andt, by the bevel gear-wheels F and Gr attached to their upper ends, these gearing into similar wheels, II and E, as shown clearly in tig. 2. It will be observed that the spur-wheel D, on the shaft D, to which E is attached, is much larger than the wheel D on the shaft with H, and that, consequently, the shaft `rc, which grinds the clay, revolves much more rapidly than t, which presses the clay down into the chamber C. The clay is pressed altere nately from opposite ends of'the chamber C, through openings of the area of the `brick to be formed,into

moulds placed there to receive it, the clay being pressed out by a reciprocating plunger or cross-head, worked to and fro in the chamber C, by means of the pitman d at each side; the pitman being attached to a slide, f, to which the plunger is connected at one end, and to aV crank on the shaft a at the oppositeend, the same as in my former putent.- The moulds for receiving the clay and shaping the bricks are raised and lowered by a crank-shaft c, working in slotted plates or yokes g, shown in gs. 2 and 3. These crank-shai`ts c haveapinion, O, attached at one end, into which the segment gear I meshes at intervals, as represented in g: 3, the genera-l arrangement and operation of these parts being similar to those described in my former patent.` In iigsnl, 2,- and 3, [represents the bar which holds the moulds in place while the clay is being pressed into them. Instead, however, of letting the moulds also rest on a ledge or shelf attached to the lower edge of this bar Z, as in my'. former machine, I mount a bar, e, in the standards 6'; this bar c being pivoted at its ends so as to permit it to lrock slightly, for the purpose of loosening the moulds after they are filled, and the brick out off by the wire 'it attached to the bar I, and thus 'permit them to be more readily detached and removed. In order to tilt these bars c, an arm, j), is attached to the shaft L, on which is mounted the segment gear I); this arm being arranged to hit the sliding bar u, by which the vertical bar v, pivoted at is tilted, causing the projection gj to` strike against e, and tip itl to loosen the mould, as represented in tig. 3. As the arm p continues to rotate, it then comes in contact with the arm attached to the bar c, at the opposite end of the chamber C, and thus to looseIi the mould at that end also. On the opposite side of the machine, as shown in tig. 3, an arm, e, is attached to cach of the rocking bars e, and to these :i1-nis weights w are attached, which return the bars e to their position again as soon as the arm j; has operated to tilt them. Onthe opposite end of shaft D( is a bevel gear, I, gear= ing intoa similar wheel, I', on theupper end of a vertical shaft, I. To the lower end of this shaft is secured a bevel-wheel, P', which gears into a. similar wheel, L', on the outer end of the shaft that carries the segmentwheel P. The wheel L gears into a similar wheel, L, attached tothe end of an oblique shaft, J, which has at its opposite end another bevel gear, J, which, engaging with a similar wheel, J, on the crank-shaft a, by 'which the reciprocating plunger or presser is operated, as already described. It will thus be seen that all the parts of the machinery must move together, and'that by this arrangement of .the gear, a positive movement of each t part at the desired time isseeured. The parts which particularly constitute my invention in this machine are the arrangenientof the gear, the rocking bars e, with their operating parts, and the shafts x and t, arranged to rotate in opposite directions within the hopper.`

1. The arrangement of the gear for operating the various parte of the machine, as herein shown and described.

2. The tilting bars e, for supporting and loosening the mould, when arranged and operated substantially as set forth.

3. The eombination and arrangement ofthe shafts x and t, with the hopper B, screen S, and screw W, substantially as herein described.
